It's a level sensor, as far as I know, threaded into the block or oil pan on the passenger side.
You probably know how to reset the oil change indicator, but for those who don't, you have to insert a paperclip or other metal object into the little hole beside the VMM and then turn the ignition key to ON. I think you just hold it for a couple seconds, it blinks, and then you go on your way. Correct me if I'm wrong.
